Clinton is the presumed front-runner for the Democratic nomination for president in 2016, were she to run, over another member of the Obama White House: Vice President Joe Biden. The vice president did not fare as well in Gallup’s poll.

Americans view Biden favorably, 46 percent to 42 percent. His favorability has been in the mid- to low-40s since he took office under President Barack Obama after enjoying a peak 59 percent to 29 percent favorability in late 2008, just after he unsuccessfully campaigned for president and accepted the vice president spot on the winning ticket in 2008.

Gallup surveyed 1,023 adults from Feb. 6 to 9 for the poll, which has an error margin of plus or minus 4 percentage points.
